If you want to get on Steam you need to get some wishlists, the more the better. If you don't get any or get not enough then after the first week (Steam raises your game on the top in the first week) your game would just sink and won't get any view/downloads. So I guess, at the current moment if placing my game on the Steam would only bury me deeper. Plus I'm not sure Steam would allow my game, shit may happen
